<p>Voltage switching sequences in transformer stations of a power grid are carried out by forming a switching model for the actually available individual switching stations of each transformer station, using an imaginary standardised model, applicable to all switching stations. This is carried out in such manner that all switchgear elements, such as isolators, power circuit breakers and earth switching breakers, are used as variable switching elements. All switchgear elements, not available in the actual switching station, are used as contact switchgear. This model, fitting the actual switching station is subjected sequentially to preprogrammed, standardised switching sequences in test run. These sequences are applicable to different switching stations. The switching runs are used for finding empirically a suitable switching sequence, which is the put into operation. Preferably each switching sequence starts with a given base position of the individual switchgear elements. The best corresponding base position is selected from several possibles.</p> |
